The sample design includes six significant steps. To illustrate this, let's consider Mike, a market researcher in a skincare company that is preparing to launch a new lotion for adult skincare enthusiasts.

Mike first identifies the target audience, which includes adults who regularly purchase skincare items.

Then, he constructs a sampling frame directly from the company's customer database, ensuring it's an accurate representation of their entire customer base.

The next step is to select a sampling method, choosing between probability and non-probability sampling techniques based on the research design.

Further, he decides on the sample size, which depends on the size and variability of the population and the research design chosen. The aim is to draw meaningful conclusions.

Finally, Mike is ready to collect the sampling data. He surveys the customers within the sample to gather insights regarding the new lotion's launch.

After collecting feedback, he validates responses to ensure the sample represents the company's varied customers, setting the stage for a successful product launch.
